This application claims the benefit of Provisional Application No. 62/195,503, filed Jul. 22, 2015, entitled “Maximizing Effective Surface Area of a Rectangular Image Sensor Concurrently Capturing Image Data from Two Lenses”. Provisional Application No. 62/195,503 is incorporated herein in its entirety.

BACKGROUND

The present invention relates to the field of multi-lens optical capture devices and, more particularly, to maximizing effective surface area of a rectangular image sensor concurrently capturing image data from two lenses.

Commercial image sensors are generally rectangular shaped due to fabrication techniques and constraints. During fabrication a relatively large rectangular surface is formed, which is subdivided into smaller rectangular geometries, each of which become an image sensor. Conventionally, a rectangular or square sensor is used as a light target for a circular (or oval) image circle from a lens. As such, there is an incongruity between the image circle from the lens (e.g., light striking image sensor) and the geometry of the sensor (e.g., rectangular). Consequently, maximizing image sensor usage has been a significant effort within the industry.

DETAILED DESCRIPTION

The present disclosure is a solution for maximizing effective surface area of a rectangular image sensor concurrently capturing image data from two lenses. In the solution, light collected by a set of lenses can be captured onto a singular image sensor. That is, the innovation utilizes a single image sensor (e.g., rectangular in shape) for two different lenses to concurrently capture light from the two different lenses. These lenses can face opposite directions or otherwise contain image data that is non-overlapping. The areas of the image sensor upon which an image circle from each of the two lenses is non-overlapping, as well. To maximize a surface area and thereby minimizing the size of the sensor to accommodate the image circles, these circles are offset at a diagonal to one another as opposed to being centered at a center point of an edge of the sensor.

FIG. 1 is a schematic diagram illustrating a set of embodiments 110, 130 for maximizing effective surface area of a rectangular image sensor concurrently capturing image data from two lenses in accordance with an embodiment of the inventive arrangements disclosed herein. Embodiments 110, 130 can be performed in the context of embodiments 210, 250, 310, 330, system 350 and/or embodiment 410. In embodiments 110, 130, simultaneous non-overlapping image circles can be produced upon an image sensor from two or more lenses within an optical capture device (e.g., camera with multiple opposing lenses).

As used herein, simultaneous image circles can include image circles which can occur at the same time in real-time or near real time. Simultaneous image circles can include, but is not limited to, synchronous image circles, concurrent image circles, and the like. Non-overlapping image circles can include shapes whose boundaries are tangential but non-intersecting. That is, image circles boundaries can be adjacent or non-convergent.

An image sensor 120 (e.g., imaging sensor) is a sensor that detects and conveys the information that constitutes an image. The sensor 120 can convert the variable attenuation of waves (e.g., as they pass through or reflect off objects) into signals, the small bursts of current that convey the information. The waves can be light 122, 124 or other electromagnetic radiation. Digital image sensors can include semiconductor charge-coupled devices (CCD) or active pixel sensors in complementary metal-oxide-semiconductor (CMOS) or N-type metal-oxide-semiconductor (NMOS, Live MOS) technologies. In one instance, sensor 120 can be a twelve megapixel sensor such as a 4:3 aspect ratio sensor.

Embodiment 110, 130 utilizes a single image sensor 120, 140 (e.g., rectangular in shape) for two different lenses (e.g., 112, 116 for embodiment 110 and 132, 136 for embodiment 130). These lenses 112, 116, 132, 1346 can face opposing directions (e.g., or otherwise include image data that is non-overlapping). The areas of the image sensor upon which an image circle 114, 118, 134, 138 can be formed from the light 122, 124 from each of the two lenses 112, 116, 132, 136 is non-overlapping, as well. For example, two images 114, 118 can be formed on a single image sensor 120 from two different opposing lenses 112, 116 of a multi-lens camera. To maximize a surface area and thereby minimizing the size of the sensor to accommodate the image circles, these circles are offset at a diagonal to one another as opposed to being centered at a center point of an edge of the sensor.

In other words, instead of dividing the region of the sensor into rectangular regions where the image circles from the lenses are centered at a half-way point along a length (e.g., 4000 pixel) of a sensor side (e.g., embodiment 130), the proposed arrangement is to establish a diagonal from a corner to an opposing corner of the image sensor, where the image circles are centered along the diagonal.

This arrangement maximizes the available surface area of the sensor (permitting larger image circles and/or smaller image sensor size) which maximizes pixel density while minimizing overall sensor costs. For example, the image circle in embodiment 114, 118 can have an increased diameter of 102 pixels (e.g., D=2102) over embodiment 130 (e.g., D=2000). In one embodiment, the lenses themselves are offset relative to each other, to ensure that the image circles are positioned along a diagonal off the sensor providing maximum usable area. In various embodiments, image circle can be within 1, 5, or 10 percent of an edge of the sensor's effective area.

View 111 illustrates one embodiment for offsetting image circles 114, 118 within a rectangular image sensor 120. In the view, the circle 114, 118 center 113, 117 can be offset by radius 127 from the width edge (e.g., 3000 pixels) of sensor 120 and offset by distance 123, 128 from the half-way line 119 along the width of the sensor 120. That is, the circle 114, 118 can be maximized by allowing an arbitrary offset for circle center 113, 117 based on sensor geometry.

View 121 illustrates an exemplary area 115 of a circle image 134 in comparison with image circle 114. In the comparison, an exemplary area 115 can be gained as a result of the offset of the embodiments (e.g., 110, 210, 250, 310, 330, 340, 350) within the disclosure. The offset can permit the radius (or diameter) of circle image to increase (e.g., radius 125 versus radius 127) which can lead to sensor maximization. For example, an increase in diameter of circle 114 (e.g., D=2102) by 102 pixel over circle 134 (e.g., D=2000) can yield a 9.4% increase in image circle area. That is, in the example, the disclosure can maximize image circles and decrease in unused image sensor area by 18.8%. It should be appreciated that exemplary area 115 can exaggerated for clarity and is not an actual representation of a optimization increase disclosed herein.

Drawings presented herein are for illustrative purposes only and should not be construed to limit the invention in any regard. It should be appreciated that one or more optimization equations and/or algorithms can be utilized to determine image circle size and/or position. It should be appreciated that the disclosure can include threshold values for establishing image circle position and/or size including, but not limited to, sensor effective area, image fidelity, and the like.

It should be appreciated that image sensor 120 can be an exemplary sensor and the disclosure is not limited to the exact sensor geometry. It should be appreciated that sensor properties can include pixel resolution (e.g., number of pixels), effective area, sensor efficiency, spectral properties, and the like. For example, sensor 120 can be a

FIG. 2 is a schematic diagram illustrating a set of embodiments 210, 250 for maximizing effective surface area of a rectangular image sensor concurrently capturing image data from two lenses in accordance with an embodiment of the inventive arrangements disclosed herein. Embodiments 210, 250 can be performed in the context of embodiments 110, 130, 310, 330, system 350 and/or embodiment 410.

In embodiment 210, the lenses 212, 216 can be positioned along a center line, where the sensor is placed at an angle 222 (e.g., rotated around a vertical axis), such that the center of the image circles align with a corner-to-corner diagonal line across the image sensor. For example, the lenses 212, 216 can be positioned at a 45 degree angle from a horizontal plane 224 (e.g., askew) instead of aligned to the width of the sensor 220.

In embodiment 250, the lenses 272, 276 can be positioned along two arbitrary diagonal lines 252, 256, where the diagonal 252 extends from a corner 254 and the diagonal 256 extends from corner 258 such that the center of the image circles 260, 262 lie on the diagonal line 252, 256 across the image sensor 270.

FIG. 3 is a schematic diagram illustrating a set of embodiments 310, 330 and a system 350 for maximizing effective surface area of a rectangular image sensor concurrently capturing image data from two lenses in accordance with an embodiment of the inventive arrangements disclosed herein. Embodiments 310, 330 and system 350 can be performed in the context of embodiments 110, 130, 210, 250 and/or 410.

Although the image circle is described and shown as a circle herein (e.g., which is common practice in the industry) some distortions of this shape are possible and are within scope of the innovation. For example, the “image circle” can be a mathematical ellipse shape (e.g., oval) or a rounded rectangle.

As defined herein, an ellipse can be a curve on a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. A circle can be a special circumstance of an ellipse (e.g., where the two focal points of the ellipse are positioned at the same point). When an ellipse is used (e.g., not a circle) with the innovation, either one of the ellipse's focal points for each image circle can fall on (+/−5 percent) the diagonal between the corner of the sensor.

As used herein, a rectangle can be any four sided Euclidian polygon with four right angles. Rectangle can include a special instance such as a square. In one instance, the rectangle can include a rounded rectangle which can be a rectangle with rounded corners.

In embodiment 310, 330, intentional distortion of the image circles can further maximize the usage of an image sensor 319, 320 area. Distortion can yield lower image quality (e.g., due to pixel resolution loss), but additional software and/or hardware fidelity corrections can be applied to lessen the image quality loss. For example, for an image circle, image pixel resolution can be 1:1 and for a distorted image resolution can be 1:0.7 resulting in a loss of image resolution/quality which can be corrected with smoothing functions and/or noise reduction algorithms. It should be more traditional and/or proprietary light manipulation techniques can be utilized to distort image circles and/or optical pathways from lenses to sensor surface.

In one instance, when panoramic images are formed from distorted circles such as an ellipse, the edges where distortion can be significant, the edges can be interpolated during stitching to enhance edge quality. That is, pixel data from each edge can be utilized to enhance the other which can improve overall edge fidelity.

In embodiment 310, an image circle 314, 316 can conform to an elongated circle (e.g., ellipse, oval) enabling maximization of sensor 319 usage. In the embodiment, the elongated circle 314, 316 can have a major axis 311 and a minor axis 313.

In embodiment 330, an image circle 324, 326 can be further distorted into a rounded rectangle 324, 326 enabling optimization of sensor 320 usage. In the embodiment, the rounded corners of rectangle 324, 326 can allow for further maximization of sensor 320 utilization.

From a manufacturing perspective, the sensor's effective area can include manufacturing flaws without affecting performance, so long as these flaws are located within an area of the sensor that is not a target for the image circle (e.g., area 318, 328). Thus, defective sensors with strategically placed defects can be utilized for maximum effect, further minimizing costs as often any defective regions of a sensor during fabrication results in that sensor rectangle being deemed defective and unusable.

In embodiment 340, additional lenses can direct image circles upon the same sensor 349. For example, an image circle from an additional two lenses can be positioned within a non-overlapping area (e.g., area 346) on the image sensor. In such a case, the original two image circles 341, 342 can be maximized, where the additional two image circles 343, 344 can be smaller and of lower pixel density. This arrangement is reasonable given that multi-lens devices (e.g., smartphones) often include multiple lenses of different resolutions. Further, in stereoscopic situations, where additional lenses are needed for depth calculations, the image density (e.g., pixel count) may be inconsistent with a primary image, yet retain the same effective utility. For example, GOOGLE'S PROJECT TANGO utilizes multiple cameras (e.g., front and back) along with infrared depth sensors. As used herein, the depth sensors and/or additional camera lenses used to determine depth can be lenses with a lesser optical density requirement than a primary lens (e.g., front and back cameras) used to produce the image. In such a situation, depth enabling lenses can intentionally be of lessor resolution, which can non-the-less share sensor space to minimize manufacturing costs and to maximize utilization of a rectangular shaped image sensor as described herein.

In embodiment 350, mixed shape sensor utilization is contemplated. In the embodiment two image circles 351, 352 can utilize a majority of the sensor 359 area. To optimize sensor 359 usage, two additional lenses can be utilized to direct light upon sensor 359 into a rounded rectangular shape to ensure optimization of sensor area.

In one embodiment, device 372 can include a set of a fixed surround imaging components for capturing a field of view of between two hundred and seventy to three hundred and sixty degrees of a horizontal plane.

In one instance, device 372 can perform image stitching, image interpolation, image correction, and the like. In one embodiment, device 372 can be communicatively linked with one or more computing devices which can permit communication of image data over a wired and/or wireless network.

In one embodiment, optical guides 374 can be placed between the lenses to direct light to assure the arrangement of the optical circles as described herein is achieved in contemplated embodiments. In one embodiment, guides 374 can be utilized to distort and/or deform image circles to achieve the distorted image circle shapes described herein.

In one instance, device 372 can include, but is not limited to, thermal imaging, infrared capabilities, low light functionality, and the like. In one embodiment, device 372 can include an array of lenses able to capture a high definition view of a real world environment.

Waveguide 374 can include a region of increased refractive index, compared with the surrounding medium. Waveguide 374 can include, but is not limited to, planar waveguides guide (e.g., vertical direction guidance), channel waveguides guide (e.g., two dimensional guidance), and the like.
